The Pearly Clamclamp (ヤマシンジュ?, lit.: "Hill Pearl"; called the Clampshell in the European version of New Play Control! Pikmin) is an enemy in Pikmin. This large bivalve has a pinkish shell, and inside, a small pearl surrounded by a clear blue membrane. This pearl can be attacked by Pikmin. One specific Pearly Clamplamp has a ship part, the Positron Generator, instead of a pearl, which works the same way. The enemy's only defense is acting like a Venus flytrap: the Clamclamp will stretch its mouth wide open, creaking like a poorly-oiled hinge, and chomp, eating any Pikmin inside. When its health is depleted, the pearl will fall out and can be carried to an Onion, where it gives 50 Pikmin. However, the enemy cannot truly die, and will continue to attack even after its pearl has been removed.

Olimar's voyage log

One would expect this creature to be a mollusk of the sea, but the fact that it is also found in the forest is typical of this planet's oddities. The pearl that rests inside appears to be one of great value, but it is actually a trap.

Reel notes

Though beautiful, this mollusk's pearls are thin and fragile.

Guide book[edit]

To lure then trap creatures that are attracted to small shiny objects, the Ploister turns undigested foodstuffs into round beads with the same secretion that makes up its shell.

The pearl-like substance has a layering that is thinner and weaker then a real Pearl, reducing it in value.

Shortly after you toss Pikmin into a pearly clamclamp, its shell will snap shut. Don't let the clam gobble up your Pikmin by ordering them in and out of the shell before it has a chance to clam up. If your Pikmin can smack the clamclamp's pearl free from the shell, they can cash it in at an onion to earn 50 seeds.

Pikmin Nintendo Power Booklet description[edit]

Pearly clamclamps survive on instinct. If a Pikmin touches its sensitive tongue, it slams shut and slowly grinds away at an easy meal. Clamclamps produce pearl-like orbs that you can cash in for 50 Pikmin seeds.

Story Mode[edit]

They only appear in The Impact Site. There are three, all of them on the beach area at the northwest. One is submerged in water, and has the Positron Generator. Another is in a small island in the pond, and the final one is on the beach itself, to the north of the area.

Challenge Mode[edit]

These are the locations of the Pearly Clamclamp in Challenge Mode. These places are in specific hard to reach places and surrounded by enemies.


Fighting a Pearly Clamclamp in The Forest Navel in Challenge Mode.

The following article or section contains guides.
The strategies presented may not be the only ones or the best ones.


There are three ways to kill the Pearly Clamclamp:

  • The first and most dangerous way to defeat this enemy is to gather about 20 to 30 Pikmin and throw them into the mouth of the Pearly Clamclamp, then when the Pearly Clamclamp starts to open its mouth wider, call them back.
  • The second and easiest way is to gather up 2 Yellow Pikmin, get them bomb-rocks, and then throw them at the Pearly Clamclamp at a reasonable distance.
  • The third way is probably the most time consuming, but is the best for zero death challenges. Bring about 5 Pikmin (any type for Pearly Clamclamps on land), then throw 3 to 5 in the mouth. When the creaking sound of the Clamclamp stops, call the Pikmin back. Repeat until the loot comes out.

Note that it can still attack after its pearl has been taken out.

Oddly, the Clamclamp has been known to take slight damage for a short time after the Pikmin have been called back, meaning that if the creature is already near death, the player can simply withdraw their Pikmin and the Clamclamp will die on its own.

With enough throwing speed, it is possible to defeat the enemy in a single cycle (i.e. before it closes its shell the first time), although this is mostly only feasible in tool-assisted superplays.[1]


There is only one place that a Pearly Clamclamp can be killed with Olimar alone. In The Distant Spring in Challenge Mode, go to the area near where the Chronos Reactor is found in Story Mode. There is a Yellow Wollywog nearby. Lure it right next to the Clamclamp, and lie down right next to it. After a few attempts, you'll be in the Clamclamp. It will try to shut on you, like if you were a Pikmin. Attack the pearl with your leader's punch then lay down if the Clamclamp and/or the Yellow Wollywog tries to attack. If you successfully do all these tactics, you will have defeated the membrane surrounding the pearl. Then get out of it, as the enemies will still try to attack. It was originally thought that this could only be done on the New Play Control! version of Pikmin, but it can be done on both versions.

Other information[edit]


  • Common name: Pearly Clamclamp. The name consists of the word "pearly", referring to the pearl it normally holds, and a combination of the words "clam" and "clamp", "clamp" meaning "to crush and squeeze". In the European version of New Play Control! Pikmin, its name was changed to simply "Clampshell", for unknown reasons; this name is a combination of "clamp" and "clamshell".
  • Japanese nickname: ヤマシンジュ?, lit.: "Hill Pearl".
  • Japanese name: ハエトリヤマシンジュ?, lit.: "Flytrap Hill Pearl"
  • Scientific name: While not entirely official, its scientific name is Lapis regrettabilis. Lapis may refer to the color of the pearls they carry, the water they inhabit, or the Blue Pikmin used to defeat them. Regrettabilis is similar to "regrettable", which may refer to how the player may regret throwing Pikmin into its mouth.
  • Internal names: Internally, this enemy is simply called shell, and the pearl is called pearl.
  • Prerelease: None.
